Contrary to the opinion of some reviewers, Theodore Tugboat was a well done, well executed children's show that was spell binding in its own way. Dennis Doherty, the late member of the rock band the Mamas and the Papas, did quite well as the voice of all the characters on the show, particularly the Harbormaster, who introduced each show.
Done on a relatively small budget, the show provided children with opportunities to confront their own inner demons (such as dealing with feelings of loneliness) by watching how the on-screen characters interacted in "the Big Harbor" - based the real life Halifax Harbor in Nova Scotia. A non-violent alternative to the space wars genre of Saturday morning children's television, the show eventually appeared in some 80 countries and was still in syndication in 2006.
Having worked on children's programs in the industry for some years - and having my interest in television piqued by appearing on children's programs as a child myself - I found Theodore Tugboat to be a worthy addition to the family of such luminaries as Captain Kangaroo and Shari Lewis. It's a plus for families and a don't miss bet for your kids!
